Forests absorb huge amounts of carbon dioxide from Earth’s atmosphere, which makes them a key part of

easing climate change. But humans may have already made the world’s largest rainforest useless in—and perhaps

even detrimental to—the battle against greenhouse gases, a new study finds.

According to the study, the carbon balance of the Amazon rainforest is damaged largely due to large-scale

human disturbance to the Amazon ecosystem, with wildfires—many deliberately set to clear land for agriculture

and industry—responsible for most of the CO2 emissions from the region and the hotter dry seasons.

“The first very bad news is that forest burning produces around three times more CO2 than the forest absorbs,”

lead author of the study Luciana Gatti said. “The second bad news is that the places where deforestation is 30

percent or more show carbon emissions 10 times higher than the places where less than 20 percent of forest is

destroyed.”

In the new study, the researchers analyzed nearly 600 measurements of CO2 and CO concentration at four

spots in the Brazilian Amazon collected from 2010 to 2018. The team found that, on average, fires poured about 1.6

billion tons of CO2 into the atmosphere each year, while healthy trees absorbed only about half a billion tons. The

team also found that, while the Eastern Amazon, which has seen historically greater amounts of deforestation over

the past 40 years, has become a place where carbon emissions are from, the Western Amazon, which has seen much

less deforestation, is neither a carbon “producer” nor a carbon sink. There, CO2 absorption by healthy forests

balances the emissions from fires.

The Amazon Basin contains about 2.8 million square miles of jungle, representing more than half of the

tropical rainforest area remaining on Earth. “Limiting deforestation, and especially wildfires, is key to changing

this dangerous trend in the Amazon. Imagine if we could keep the Amazon from fires, the forest could be a carbon

sink,” Gatti said. “But we are doing the opposite—we are accelerating climate change.”

阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。

They always say, “There is no time like the present.” And that is why “being in the now” is important,

especially when you travel. 36 Here are some easy ways to offer help:

Do nothing.

3 7 Lie in bed in your hotel room and stare into space. Enjoy the complete silence. Take note of how

relaxed you already feel because you are not rushing to anywhere or trying to figure out how to get something

done.

Listen, really listen.

People often confuse the terms “hear” and “listen”. Hearing is receiving sounds by the ear, an act that simply

happens. 3 8 Concentrate on the sounds around you, even the gentle sound of your breathing. Try to mentally

point out certain sounds that your ears did not pick up before this.

Document almost everything.

Turn on the digital notepad on your smart phone, get a small notebook from the airport and write everything

down during your holiday. At the end of your day, document what you did, where you went, how you got there,

what you ate, who you met, etc. 3 9

Pay attention to your thoughts.

Your thoughts are louder than you think. They are just often drowned out by a garble of noises from your

surroundings. Being on holiday is an excellent opportunity to pick at your own thoughts because you are removed

from the noise and circumstances. 40

A．Copies of the relevant documents must be filed.

B．It will not take up too much of your time but it makes a good travel memory.

C．Staying still and doing absolutely nothing is the easiest.

D．Stick some ticket stubs or receipts in it while you are at it.

E．Listening, however, is something you consciously choose to do.

F．So how can you grasp the concept of “being in the now” while you travel?

G．It is a good time to pay attention to your thoughts because it helps put things into perspective.
